SPECIFIGATION forming part of Letters :Patent No. 264,926, dated September 28, 1882.

(No model.)

To all whom it mag/concern:

Be it known that I, DANIEL OARLOUGH, a citizen of the United States, residing at Paterson, Passaic county, State of New Jersey, have invented a new and useful Improvement in (Jar-Oouplings, of which the following is a specification, reference-being lhad to the aecompanying drawings, forming a part thereof, in which- Figure 1 is a side view of my newly-invented coupling, showing the parts coupled together. Fig. 2 is a horizontal'section of the same. Fig.3 is a plan. Fig. 4 is a sectional plan of the same. Fig. 5 is a front View of the coupling, and Fig. 6 is a section through the couplin g-pins.

a represents the coupling-box, the front of which is constructed open and bell-shaped, and is therebyV adapted to meet any differences in the height of the 'cars to be coupled, or any lateral differences therein, and guide the coupling-link c into engagement with the couplingpin l). i

a/ represents that part of the coupling which is to be attached to the cars, which may be attached thereto by any of the known means now employed for that purpose. i e2 represents the openingin the coupling-box.

b represents the coupling-pin, which is provided with a headof eylindrical form sufficiently large to prevent the escape of the pin through the hole provided for the same in the coupling-box a. The coupling-box a is dished or hollowed out Where the coupling-pin b enters the same. The cylindrical part of the pin b rests in' the dish t'of the coupling-box a, and readily yields to the touch of the couplinglink c.

c represents the coupling-link, which is constructed with an open center, which gives am ple` space for the eoupling-pin b to work freely therein. The pivot end of the coupling-link c is sufficiently swelled to provide for a suitable hole through the same to accommodate a pivot, g, without weakening the link c. The pivotg Works in suitable slots, f, formed in the sides of the coupling-box a. The pivot g may be made like ordinary bolts, kept in position by means ofa screw-nut, Sto. The free end e of the coupling-link c is constructed with a featheredge, which allows the links to operate freely over each other when coupling the cars. The top of the coupling-box a is provided with a slot, Ir, back of the coupling-pin b, which admits of the coupling-pinls back ward movement When the same is brought into engagement with the free sharpened end of the couplinglink c, which carries the pin b backward until the link c is allowed to pass under the coupling-pin b, which, alter the solid part of the link c has passed in its movement beyond the end of the pin b,-the coupling-pin b, by force of gravity, drops down in the open center of the link c, by which action of the pin b the cars are coupled together. The bottom ofthe coupling-box a is provided with a receivinghook, d, which holds the coupling-pin b in position for draft.

Operation: The coupling-box a having been attached to `the cars by any. of the ordinary means employed for that purpose, the link c is placed in position in the coupling-box and secured therein by neans of the pivotg in the slotsf. The coupling-pin b is now put in position, which places the couplin g devices in position for automatic action. coupled are brought together `therefor when the coupling-link o presents itsrslarpened end e to the bell-mouth a' of the coupling-box, and is directed thereby into engagement with tle coupling-pin b, which recedes in its engagement with the link c until the solid part e of the link c has passed under and beyond the end of the pin b, which releases the couplingpin b from the action of the coupling-link c, which causes the pin b, by force of gravity, to fall down in the open center of the link c, automatically coupling the cars together. The cylindrical form of the head of the couplingpin b facilitates the pinls return to its perpeudicular position by relieving the pin from frietion on acconnt of its small bearing-surface on the coupling-box. My coupling Works equally well with one or two links. The ends of the links being sharpened causes them to pass over and under each other freely. The coupling-pin b may be constructed with a point at the bottom to fall ina slot in the bottom of the coupling-box; or an opening may be made in the coupling-box suffieien tl y large for the couplin gpin b to pass through the same, if required, to guard against the pin raising out of position .75 The cars to be ICO /under heavy draft, &o. The coupling-liuk c is The combination of the coupling-box a a' az, conpling-links c, coupling-pin b, pivots g, slots f, slot lc, dish i, latch-hook d, and sharpened end c, substantially as and for the purpose set 15 when it becomes necessary in the operation of forth.

coupling, and then returns to its horizontal position.

Having described my newly-invented coupling and its operation, what I claim as my invention, and desire to secure by Letters Patent, is-

DANIEL CARLOUGH.
